|---|---|---|
| Test scope | Only applicable to off-grid systems | Covering off-grid and grid-connected systems |
| Core content | Test conditions and methods | Test conditions, methods, reliability test |
| Key changes | No requirements for grid-connected systems | New grid-connected system test requirements |
Test conditions and preparation
Environmental conditions
The environmental conditions for the system test shall meet the following requirements:
- Altitude: not exceeding 1000 m
- Temperature range: indoor 25°C ± 5°C, outdoor 0°C to +40°C
- Relative humidity: not more than 90%
Test equipment and connection method
The main instruments and equipment required for the test include:
- Wind turbine simulator: consists of an electronic control platform, a three-phase asynchronous motor, a torque sensor, etc. (Figure 3)
- DC power supply: used for system testing
- AC power grid: meets the system power requirements
Test methods and implementation recommendations
Test methods for main components
The main components of the system include wind turbines, photovoltaic panels, controllers, inverters and batteries. The test methods for each component are as follows:
- Wind turbine: Tested in accordance with GB/T 19068.2 and GB/T 19068.3
- PV module: Tested in accordance with GB/T 9535
- Controller: Including tests of off-grid and grid-connected controllers, involving indicators such as voltage, current, and power (Figure 1, Figure 2)
- Inverter: Off-grid type is tested in accordance with GB/T 20321.2, and grid-connected type is tested in accordance with GB/T 30427
- Battery: Energy storage lead-acid battery is tested in accordance with GB/T 22473
Comprehensive performance test and reliability test
Off-grid system
The comprehensive performance test of the off-grid system includes:
- Power quality test: output frequency stability, voltage regulation, waveform distortion test
- Protection function test: undervoltage, overvoltage, short-circuit protection and other function verification
- Display function test: check the accuracy and clarity of the system status display
- Wind turbine no-load voltage shock test: continuous operation for 3 minutes, no damage to the system
Grid-connected system
The comprehensive performance test of the grid-connected system includes:
- Maximum power tracking test: test the inverter output power at different speeds
- Protection function test: low voltage cut-off and reset, overvoltage protection and other tests
- Display function test: check the accuracy of the grid-connected status display
- Wind turbine no-load voltage impact test: Continuous operation for 3 minutes without system damage
Implementation suggestions
To ensure the accuracy and reliability of the test, it is recommended:
- Follow the standard process: Strictly prepare and execute the test in accordance with the requirements of GB/T 19115.2—2018
- Regularly maintain equipment: Ensure that all test instruments are within the metrological validity period and maintain their accuracy
- Train professionals: Operate by personnel with professional knowledge and experience
- Data management: Properly preserve test records to facilitate subsequent analysis and report writing
